Title: Signal generating device
Inventor: MUROOKA FUMIO
IPC: H03K3/03
Filed: 1992-06-26
Abstract: A signal generating device according to the present invention is a device for generating a signal.  The device includes a crystal oscillating element and an inverter connected in parallel with the crystal oscillating element.          The device is arranged to adjust the amplitude of a signal produced at an input side of the inverter and to capacity-couple the signal produced at the input side of the inverter to an amplifier circuit so that the signal produced at the input side of the inverter is amplified.  Accordingly, it is possible to realize a simple construction which includes a reduced number of terminals, which is suited to high-density mounting or is suitably formed as an integrated circuit, and which can be easily reduced in cost.

Title: Filter arrangement
Inventor: TITSCHER GERHARD
IPC: H02M1/12
Filed: 1990-12-07
Abstract: A filter arrangement is useful for filtering and damping harmonics and for shifting resonance points in electric networks. To this end, a first energy-absorbing damping element (Rp21) is connected in parallel with a series arrangement consisting of a first inductance (Lp2), a first capacitance (Cp21) and a fourth capacitance (Cp22). This parallel arrangement is connected in series with a parallel path consisting of a second inductance (Lp3) and a second capacitance (Cp3), as well as with a third capacitance (C1). In addition, a second energy-absorbing damping element (Rp41) is connected in parallel with the series arrangement consisting of the fourth capacitance (Cp22) and the second capacitance (Cp3). The use of this filter arrangement in the case of two tuning frequencies permits strong damping of harmonic currents with frequencies close to one of the two tuning frequencies, without significant losses due to currents with the operating frequency.

Filed: 1992-12-22
Abstract: A method is disclosed for integrating a plurality of discrete subprograms with a main program. The method enables the main program to intestate any discrete subprogram stored in its directory with the main program. The method includes the step of identifying each discrete subprogram stored in the directory of the main program and creating a cross reference array to enable the main program to access the plurality of subprograms. In addition to creating the cross reference array, an event reference list of the main program is updated, enabling commands of the subprogram to be given key and menu assignments, thereby further integrating the subprogram with the main program. Similarly, the subprogram can be removed from the main program simply by deleting the subprogram from the directory of the main program.  Further features of the subject invention include a method for enabling the subprogram to request the main program to perform main program functions, and a method for limiting the number of subprograms loaded in the address space of the computer.

Title: Image processing with anti-forgery provision
Inventor: NISHIKAWA EIICHI
IPC: B41J2/525
Filed: 1993-02-24
Abstract: A discriminating circuit discriminates the degree of similarity between an image represented by an input image signal and a predetermined specific image. A CPU outputs a pattern-level selecting signal based upon the results of discrimination performed by the discriminating circuit. A pattern adding circuit modulates an internally stored specific pattern in accordance with an added-color designating signal and pattern-level selecting signal produced by the CPU, and adds the modulated specific pattern to the image signal.      As a result, a pattern specific to the apparatus is added in a reliably identifiable manner to an image output having a high probability of containing the specific original. In the case of an image output having a low probability of containing the specific original, the specific pattern is added to this image output in such a manner that the picture quality thereof is not diminished by the pattern.

Patent CA-2102997-A1 (CA)
Inventor: PETERSON JOHN
IPC: G08B13/18
Filed: 1993-11-12
Abstract: An arrangement and method for processing signals from infrared microwave and/or ultrasonic intrusion detectors is disclosed which allows the signal to be processed at different amplitude levels to recognize different signal characteristics.  This capability to analyse the signal at different values allows further customizing of the system for particular applications and provides information useful in recognizing and dealing with unwanted signal changes typical of the environment which can effect the reliability of the alarm criteria and/or a trouble condition criteria.  An assessment of the environment in a preferred aspect allows customizing of the alarm criteria to take into account the operating environment of the particular sensor or sensors.  The system also accommodates increasing the effect on certain portions of the signal when considering the net overall effect of the signal.  This results in more signal information being available to assess possible conditions which could lead or contribute to the generation of false alarms.
